6. Prospective and longitudinal human studies of lead and cadmium exposure and the kidney
Sammanfattning : Cadmium and lead accumulate in humans and can have toxic effects. Exposure to cadmium is well known to cause kidney damage. Cadmium binds to metallothioneins, proteins that play a role in cadmium transport. LÄS MER
7. Cellular Responses to Arsenite and Cadmium - Mechanisms of Toxicity and Defense in Saccharomyces cerevisiae
Sammanfattning : All biological systems have to cope with a wide range of metals that are present in the environment. Metals can be essential or beneficial for life, inert or non-essential and toxic, often depending on their chemical form and concentration. Most organisms have evolved defense mechanisms in order to deal with toxic metals. LÄS MER
8. Batch Sorption Studies of Aqueous Cadmium and Lead from Contaminated Water onto Selected Biosorbents
Sammanfattning : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies. LÄS MER
9. Equilibrium and Kinetic Batch Studies of Cadmium and Lead sorption using Low Cost Biosorbents
Sammanfattning : Agricultural wastes; Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were evaluated for uptake of aqueous Cd2+ and Pb2+ ions in single- and binary-component solutions. Untreated, base-treated and peroxide-treated biomasses were employed in batch studies. LÄS MER
10. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae
Sammanfattning : Plants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. LÄS MER
